I spent a week in mid-June exploring the Indiana Dunes National Lakeshore. I have to confess that I had never taken the time to tarry there longer than was necessary to scramble to the top of Mt Baldy. OK, full confession--I always just thought of the Indiana Dunes as a signpost on the road to Chicago (my boyhood home) and assumed they could never hold a candle to wonderful dunes of Michigan (my adopted home).
Was I wrong! I had intended to spend a few days, and ended up exploring this wonderful treasure for a week and wishing I had more time. Indiana Dunes National Lakeshore, and the Indiana Dunes State Park, together protect over 16,000 acres of dunes, oak savannas, swamps, bogs, marshes, prairies, rivers, and forests--not to mention over 16 miles of beautiful Lake Michigan beach.
The National Park Service describes the Indiana Dunes as "a treasure of diverse natural resources located within an urban setting." Bordered by Gary in the West and Michigan City in the East, the dunes are also bisected by the huge industrial complex of Portage and the Port of Indiana. But literally within the shadows of industry, a natural jewel continues to shine.
The centerpiece of the dunes is the Great Marsh (pdf). Though much reduced from its historic size, at 10 miles long and a half mile wide, it remains the largest interdunal wetland on Lake Michigan. These dunes and wetlands were the inspiration for Dr. Henry Cowles, whose pioneering 19th century studies of dune succession earned him the title of "the father of plant ecology" and led to a decades long battle to save the Indiana Dunes.
Spiderwort were blooming profusely when I hiked the Cowles Bog Trail (pdf), probably my favorite in the park. This wonderful trail affords a close encounter with the fabled Great Marsh, and also includes a foray into the most isolated and well preserved dunes in the park.
